Electrochemistry of self-assembled monolayers of iron protoporphyrin IX attached to modified gold electrodes through thioether linkage
Article Abstract:
The attachment of iron(III) protoporphyrin IX (Fe(III)PP) and iron(III) hematoporphyrin (Fe(III)HP) to dimercaptoalkane-modified gold electrodes is discussed. Novel films using dimercaptoalkanes as spacers between electrode and redox centres are made up of a single monolayer and are very heterogeneous.

Molecular orientation of Langmuir-Blodgett films of designed heme protein and lipoprotein maquettes
Article Abstract:
A study was conducted to analyze the molecular orientation of Langmuir-Blodgett films of designed heme protein and lipoprotein maquettes. A continuous-flow Milligen 9050 solid-phase synthesizer was utilized to synthesize the peptides. The 31-amino acid peptides were then dissolved in a 100 mM ammonium hydrogen carbonate buffer. Experimental results indicated that both hemeprotein maquette and palmitoylated heme protein maquette lie flat with the alpha-helices parallel to the air-water interface when spread and equilibrated at low surface pressure.

Engineering oriented heme protein maquette monolayers through surface residue charge distribution patterns
Article Abstract:
It has been possible to design and synthesize four-alpha-helix bundle proteins that accommodation heme groups to function as molecular 'maquettes' of more complex natural electron-transfer proteins. This research compared three related synthetic heme protein maquettes.
